Communication apparatus and reception history deleting method

ABSTRACT

In a communication apparatus capable of storing an incoming-call history, the communication apparatus which has a function of deleting the incoming-call history is provided. A user is urged to input setting information for setting up control of the incoming-call history, through an operation part  6  and a display part  8 . A call register control setting part/call register control part  11  judges whether the incoming-call history is to be deleted or left, based on the inputted setting information, stores the incoming-call history in a memory  5  for outgoing-call/incoming-call history, and further automatically deletes the incoming-call history whose caller&#39;s phone number was not referred to by the user, in the incoming-call histories referred to by the user.

TECHNICAL FIELD

The present invention relates to a communication apparatus, such as a cellular telephone, which has a phone book function and an incoming-call history display function. The present invention particularly relates to a solution to current problems: a problem of a single-ring trap call which leaves a caller's phone number in a call register in order to make a user call back the caller's phone number according to the call register, to be connected to a number, such as a dial Q2, which will charge the user a large amount of communication charge, or a problem of making a called party call back a caller who is unwilling to pay communication charge, so as to impose paying the communication charge on the called party though it is the caller side to have business to call.

BACKGROUND ART

FIG. 10 shows an example of a structure of a conventional cellular phone based on the cellular phone described, for example, in Japanese Unexamined Patent Publication No. JP2000-295324.

Now, operations will be explained. The cellular phone shown in FIG. 10 has a ringing number-of-times measurement part or a ringing time-period measurement part, and measures a length from a reception of a call to a disconnection of the call. Its object is to show a cellular phone user how much a caller wanted to talk over the phone (how much the caller expected to talk over the phone), by displaying a caller's phone number and a ringing time period called by the caller to be corresponding each other in an incoming-call history. In the latest cellular phones, since a call sending operation can be easily performed for a caller's phone number displayed in the incoming-call history, the following problems can not be fully avoided by just displaying a ringing time period next to the incoming-call history a problem of a user's accidentally sending a call or unintentionally calling back a number left in the call register in order to know what it was.

In the display of the incoming-call history described in the conventional Japanese Unexamined Patent Publication No. JP2000-295324, a caller's phone number is surely displayed for a call which notifies the caller's phone number. Then, when displaying the incoming-call history, since a call sending operation can be easily performed for the number left in the call register, the user would accidentally send a call to the number.

In addition, if the number is left in the call register, there is a high possibility of performing a call sending operation in order to know what it was, because the user mentally becomes uneasy to worry whether it relates to business or not, or it is an important call from someone or not.

Consequently, there will be problems: a problem of being connected to a number, such as a dial Q2, which will charge the user a large amount of communication charge, or a problem of making a called party call back a caller who is unwilling to pay communication charge, so as to impose paying the communication charge on the called party though it is the caller side to have business to call.

It is an object of the present invention to provide an apparatus or a method for a user to easily select how to leave data in a call register. With regard to how to leave data in the call register, the present invention particularly allows a user of a cellular phone or a communication apparatus to set how to leave data in the call register based on an user's definition, for example, by setting the case in which a caller's phone number should be left in the call register or the case in which even the incoming-call history is not left in the call register.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiment 1

FIG. 1 is a block diagram showing a structure of a cellular phone relating to the present invention. A cellular phone will be described as an example. In FIG. 1, 1 denotes an antenna for transmitting and receiving a wireless signal, 2 denotes a wireless part for performing modulation/demodulation and data conversion at the time of reception and transmission, 3 denotes a control part for controlling each part of the cellular phone or performing transmission, reception, analysis, etc. of a message to/from a communication party, 4 denotes a ROM (Read Only Memory) storing various programs for controlling each part, and 5 denotes a memory (call register memory) for storing an outgoing-call history, an incoming-call history etc. of the cellular phone. 6 denotes an operation part for a user to start various functions of the cellular phone, 7 denotes a phone book memory (phone book) for storing phone book data, such as a name, a telephone number, an address, and an e-mail address, 8 denotes a display part for displaying information, states, etc., such as functions driven by operations of the operation part 6, etc., and 9 denotes a speaker for outputting a speech etc. and 10 denotes a microphone for inputting a speech. 11 denotes a call register control setting part/call register control part, which is a part of the control part 3, for performing a control being a core of the present idea. It is acceptable that a memory for the phone book memory 7 is also for the memory 5 for storing an outgoing-call history, an incoming-call history, etc. of the cellular phone.

The call register control setting part/call register control part 11 can be divided in two functions: a call register control setting part for setting up control information on saving/displaying etc. of an incoming-call history, and a call register control part for executing processing, such as saving/deleting of an incoming-call history generated depending upon a received call, based on the setting information (control information) which has been set up. The setting information (control information) is stored in the memory in the cellular phone (for example, a memory in the control part 3 or the memory for outgoing-call/incoming-call history). A memory (recording area) for recording the setting information (control information) can be called a setting information memory or a control information memory.

Although the two functions of the call register control setting part and the call register control part are collectively displayed in FIG. 1 as one structure element, it is also acceptable to arrange the two parts as separate structure elements.

Now, operations will be explained. Incidentally, “to leave X X X” has the same meaning as “to save X X X”, and indicates to store (record) X X X in the memory.

FIG. 2 shows a processing flow at the time of a call incoming into a cellular phone. Each processing shown in FIG. 2 is executed by the call register control setting part/call register control part 11.

It is judged which of “to leave” or “not to leave” a call history in the call register is set up as a setting of the cellular phone (ST1). When “not to leave” (NO at ST1) is set up, processing relating to the call register is ended with leaving nothing in the call register. When “to leave” (YES at ST1) is set up, it is checked whether the incoming call is with “presentation of a caller's phone number” or not (ST2). The incoming call with “presentation of a caller's phone number” indicates the case that the number (telephone number) of a caller is notified”.

When there is no “presentation of a caller's phone number” (NO at ST2), “missed calls” and “time of calls” are registered in the call register (ST3), and the processing relating to the call register is ended. When there is “presentation of caller's phone number” (YES at ST2), “phone book search” of checking whether the same number as the “caller's phone number” is registered in the “phone book” is performed (ST4). As a result of the “phone book search”, when there is no coincident number (NO at ST5), the “telephone number” in the “caller's phone number” and the “time of calls” are registered in the call register, and the processing relating to the call register is ended (ST7). When there is a coincident number (YES at ST5), “the party name registered in the phone book”, “telephone number”, and “time of calls” are registered in the call register, and the processing relating to the call register is ended (ST6).

Next, an example of operations where another processing is added to processing of FIG. 2 will be explained with reference to FIGS. 3 through 6. In FIGS. 3 through 6, processing with the same step number as that in FIG. 2 indicates the same processing as explained in FIG. 2. Moreover, the processing in FIGS. 3 through 6 is executed by the call register control setting part/call register control part 11.

FIG. 3 shows a processing flowchart in which processing of ST8 is added to the processing flow of FIG. 2 to be between the processing change from ST1 to ST2. As another setting in the cellular phone, the processing ST8 of checking whether the setting is to leave a “caller's phone number” or not is added. After checking whether the setting is to leave a “caller's phone number” (ST8), when the setting is not to leave a “caller's phone number” (NO at ST8), only “missed calls” and “time of calls” are set in the call register, and the processing is ended (ST3). When the setting is to leave a “caller's phone number” (YES at ST8), the same processing as those after ST2 of FIG. 2 is performed.

FIG. 4 shows a processing flowchart in which processing of ST9 is added to the processing flow of FIG. 3 to be after the “phone book search processing” of ST4.

As another setting for the call register in the cellular phone, the processing ST9 of checking whether a caller's phone number is registered in the phone book memory or whether the setting is to leave a caller's phone number is added. Regarding the “caller's phone number” which is not registered in the “phone book”, it is checked whether the setting is to leave a “telephone number” in the call register (ST9). Regarding the “caller's phone number” which is not registered in the “phone book”, when the setting is not to leave a “telephone number” in the call register (NO at ST9), only “missed calls” and “time of calls” are set in the call register and then the processing is ended. (ST3). In the case of the caller's phone number being registered in the “phone book” or in the case that the “caller's phone number” is not registered in the “phone book” but the setting is to leave the caller's phone number in the call register (YES at ST9), the processing is the same as those after the processing ST5 which follows the “phone book search processing” (ST4) of FIG. 3. The “missed calls” and “time of calls” are left in the call register as the processing in the case of NO at ST9 (ST3). However, it is also acceptable not to leave the incoming-call history, as a setting of the cellular phone.

In the processing of ST9, the phone book search processing (ST4) is executed at ST4, and it is judged whether the caller's phone number is registered in the phone book or not.

In the case of the caller's phone number being registered in the phone book, it becomes YES at ST9. In the case of the caller's phone number not being registered in the phone book, as explained above, it is judged at ST9 based on the setting (setting information) whether the caller's phone number is to be left or not.

FIG. 5 shows a processing flowchart in which processing of ST10 is added to the processing flow of FIG. 4 to be between the processing change from ST5 to ST7.

As another setting in the cellular phone, the processing performed in the case that a ringing time period is shorter than the setting time period and the cellular phone user does not answer the incoming call in the state of “ringing” is set up (ST10). As this setting, when the setting is set up of not leaving a “telephone number” in the call register (YES at ST10) in the case that the ringing time period is shorter than the setting time period, only “missed calls” and “time of calls” are set in the call register and the processing is ended. The processing performed in the case that the “ringing time period” is longer than the setting time period and the cellular phone user does not answer the incoming call (NO at ST10) in the state of “ringing” is described as ST7 of FIG. 4.

The state of “ringing” is obtained by measuring a time from receiving a “call setting request message” from a communications network to receiving a “disconnection message” from the communications network and the state of “ringing” is compared with the “setting time period” set in advance in the cellular phone. The “missed calls” and “time of calls” are left in the call register as the processing of ST3. However, it is also possible to leave nothing in the call register, as a setting in the cellular phone.

FIG. 6 shows a processing flowchart in which processing of ST11 is added to the processing flow of FIG. 4 to be between the processing change from ST9 to ST5.

As another setting in the cellular phone, the processing (ST11) of checking whether the setting is set up of not leaving the “caller's phone number” in the call register when a ringing time period is shorter than the setting time period and the cellular phone user does not answer the incoming call in the state of “ringing” is added. In the case that the setting is set up of not leaving “caller's phone number” in the call register when a ringing time period is shorter than the setting time period and the cellular phone user does not answer the incoming call in the state of “ringing” (YES at ST11), only “missed calls” and “time of calls” are set up in the call register and the processing is ended. In the case that a ringing time period is longer than the setting time period and the cellular phone user does not answer the incoming call in the state of “ringing”, or in the case that leaving the “caller's phone number” in the call register is set up (NO at ST11), it goes to the processing of ST5. The processing performed in the case that a ringing time period is longer than the setting time period and the cellular phone user does not answer the incoming call in the state of “ringing” (NO at ST11) is the same as the processing after ST5 of FIG. 4. The “missed calls” and “time of calls” are left in the call register as the processing of YES at ST11 (ST3). However, it is also possible not to leave an incoming-call history as a setting of the cellular phone.

FIG. 7 shows an example of screen changes at the time of performing a setting in the cellular phone in order to realize each processing shown in FIGS. 2 through 6. Each setting of the cellular phone is performed by the operation part 6 and the display part 8 of FIG. 1. Setting information (control information) inputted by the user through the operation part 6 and the display part 8 is stored in the memory in the cellular phone, by the function belonging to the call register control setting part of the call register control setting part/call register control part 11. The stored setting information (control information) is used for the case of saving/deleting an incoming-call history, by the function belonging to the call register control part of the call register control setting part/call register control part 11.

Correlation between the setting information (control information) to be set up in FIG. 7 and the operations explained with reference to FIGS. 2 through 6 is as follows:

-   -   (1) “a call register setting” of FIG. 7 is used in the         processing of ST1.         -   In the case of selecting “1. to leave incoming-call             history”: YES at ST1         -   In the case of selecting “2. not to leave incoming-call             history”: NO at ST1     -   (2) “caller's phone number processing 1” of FIG. 7 is used in         the processing of ST8.         -   “1. not to leave a caller's phone number in a call             register”: NO at ST8.         -   “2. to leave a caller's phone number in a call register”:             YES at ST8.         -   “3. to conceal a caller's phone number”: corresponds to the             execution of processing of ST8→SS5→ST7.     -   (3) “caller's phone number processing 2” of FIG. 7 is used in         the processing of ST9.         -   “1. to leave all caller's phone numbers”: YES at ST9 (YES             unconditionally)         -   “2. to leave only caller's phone numbers left in a phone             book”: NO if it does not correspond to the above 1 at ST9.     -   (4) “processing at the time of un-answering: not to leave in the         case that a ringing is shorter than the setting time period” and         “What is the limit of seconds of a ringing not to leave in the         call register? ” of FIG. 7 are used at ST10 of FIG. 5 and at         ST11 of FIG. 6.         -   “YES”: YES at ST10 of FIG. 5, YES at ST11 of FIG. 6.         -   “NO”: NO at ST10 of FIG. 5, NO at ST11 of FIG. 6.

First, the menu screen of the cellular phone is displayed and “7. call register setting” in the menu is selected (ST21). Then, in the displayed “call register setting” screen, if “2. Not to leave incoming-call history” is selected (ST22), it goes to a usual idle screen. In the screen of “call register setting”, when “1. to leave incoming-call history” is selected (ST23), the next “caller's phone number processing 1” screen is displayed. In the “caller's phone number processing 1”, when “1. not to leave caller's phone number in call register” is selected (ST24), it goes to a usual idle screen. In the “caller's phone number processing 1”, when “2. to leave caller's phone number in call register” or “3. to conceal caller's phone number” is selected (ST25), the next “caller's phone number processing 2” screen is displayed. In the “caller's phone number processing 2”, when either one of “1. to leave all caller's phone numbers” or “2. to leave only caller's phone numbers registered in phone book” is selected (ST26), “processing at the time of un-answering” screen is displayed. In the “processing at the time of un-answering”, when “2. NO” is selected (ST27) for the display of “not to leave in the case that a ringing is shorter than setting time period”, it goes back to a usual idle screen. If “1. YES” is selected (ST28), the next “What is the limit of seconds of a ringing not to leave in the call register?” is displayed. Then, when time is input (ST29), it goes to a usual idle screen.

In the “caller's phone number processing 1” of FIG. 7, when “3. to conceal a caller's phone number” is selected (ST25), selection processing of “to leave caller's phone number” (ST8) in FIGS. 3 through 6 goes to “YES” unconditionally.

Next, in the “registered in phone book” (ST5) of FIG. 3, FIG. 4, and FIG. 6, it goes to “NO”. Then, in the processing of “leave telephone number and time of calls” (ST7), the caller's phone number is also left (recorded). In the case of leaving the caller's phone number, when the call register is displayed, it is set not to directly display a “caller's phone number” but to display “caller's phone number attached” as shown in FIG. 8. Information is left in the call register so that “caller's phone number attached” is displayed for a caller's phone number when the display part 8 displays the incoming-call history.

In the case of the processing flow of FIG. 5, at the “registered in the phone book” (ST5), it goes to “NO”. At the judgement of “ringing longer than setting time period” (ST12), it goes to YES. Similarly, at the processing of “leave telephone number and time of calls”, it is set not to directly display a “caller's phone number” but to display “caller's phone number attached” as shown in FIG. 8 when displaying the incoming-call history.

At the time of displaying the incoming-call history, when the user selects the “caller's phone number attached” for a history displayed with “caller's phone number attached” as shown in FIG. 8, an actual “caller's phone number” is displayed (ST31).

When the incoming-call history as shown in FIG. 8 is displayed by the operation of the cellular phone user, and the user moves a cursor and checks the contents of the incoming-call history from the top in order, even in a case of no caller's phone number being displayed for the first incoming-call history of “caller's phone number not attached” and for the second incoming-call history of “missed calls”, “time of calls”, and “caller's phone number attached”, at the time of closing the screen of the incoming-call history, the first and the second incoming-call histories are automatically deleted from the call register. Then, at the time of displaying the screen of the incoming-call history next time, the incoming-call history as shown in FIG. 9 is displayed.

In the example of FIG. 9, after the screen of the incoming-call history has been displayed once, an incoming-call history whose setting is not to store a caller's phone number is automatically deleted. The call register control setting part/call register control part 11 executes processing to delete. The call register control setting part/call register control part 11 receives a notification of the incoming-call history having been displayed, from the display part 8, and deletes an incoming-call history based on the received notification.

In the present Embodiment, have been described the cellular phone and the communication apparatus, having the phone book function and the function of the call register, in which it is possible to set up leaving or not leaving an incoming-call history in the call register, concerning any incoming calls, as a setting of the cellular phone or the communication apparatus.

Embodiment 3

In the above-mentioned Embodiments 1 and 2, a cellular phone is used as an example of a communication apparatus (communication terminal), for describing explanations. However, it is not restricted to this. Any communication apparatus (communication terminal) having a function of storing an incoming-call history can also be used instead of the cellular phone.

Industrial Applicability

In the communication apparatus (cellular phone or communication equipment) and the communication method according to the present invention, it is possible to execute processing for an incoming call at the time of the call incoming, by a user's setting up of setting information which defines a control relating to an incoming call, in the cellular phone and the communication apparatus. Then, based on such setting and processing, it is possible to create a call register according to the necessity of the user of the cellular phone and the communication apparatus.

Moreover, by dint of setting the setting information, it is possible for the user of the cellular phone and the communication apparatus to prevent and control to carelessly call the number displayed on the incoming-call history resulting in the user's being charged communication charge. Accordingly, it is possible to take measures against evil incoming calls.

Moreover, relating to an incoming call with no presentation of a caller's phone number, an incoming call whose caller's phone number is not displayed in the incoming-call history according to the intention of the user of the cellular phone of the communication apparatus, and an incoming call whose caller's phone number is not displayed according to the setting of displaying a caller's phone number by the operation of the user of the cellular phone of the communication apparatus, since such incoming calls have no use value if they are left, by way of deleting them at the time of the user's confirming their incoming and of leaving only incoming calls with a presentation of a caller's phone number and having use value to be redialed based on the incoming-call history, it is possible to effectively utilize the limited memory secured for the incoming-call history.

Moreover, according to the communication apparatus (portable terminal or communication equipment) and the communication method of the present invention, since it is possible to delete an incoming-call history, execution of an unnecessary reply based on the incoming-call history can be prevented.

Moreover, it is possible to control a call register based on setting information (control information). Being provided with a screen on which setting information (control information) can be easily changed, a user can flexibly change a saving situation of a call register.

Moreover, by saving an incoming-call history based on telephone numbers registered in the phone book, an unnecessary incoming-call history can be automatically deleted.

Moreover, by setting a continuation time period of a call ringing state in advance, it is possible to control a call register based on whether or not the call ringing state continues longer than a specific time period since the call incoming.

By setting up not to display a caller's phone number when displaying an incoming-call history and by automatically deleting the incoming-call history when the user does not refer to the caller's phone number, it is possible to save the time and effort for deleting an unnecessary incoming call history and to prevent execution of an unnecessary reply.

Furthermore, by judging whether a caller's phone number is to be displayed or not based on telephone numbers registered in the phone book when displaying an incoming-call history, it is possible to distinctively display an incoming-call history which has a high possibility of being needed by the user, and by automatically deleting the incoming-call history when the user does not refer to the caller's phone number, it is possible to save the time and effort relating to the incoming-call history and to prevent execution of an unnecessary reply.
